Rep. Al Green might have been the first to call for another impeachment vote after reports circulated of President Trump’s alleged “shithole countries” comment in the Oval Office, but he wasn’t the only one with impeachment on his mind.

Convinced that Trump’s comment was racist, Cornell law professor Josh Chafetz put together the case for impeachment of the president in a series of tweets Thursday.

In my view, a constitutionally conscientious legislator could conclude that a demonstrated pattern of racist conduct by a president constituted a high crime or misdemeanor for impeachment purposes.

An offense against the spirit animating the Reconstruction Amendments is just as much an anticonstitutional political offense as an offense against the separation of powers or any other constitutional principle—more so, really, in light of American history.
